Refilling Fire Extinguishers
A Fire extinguisher is a passive product that needs to stay in a ready state at every point of time. Because a fire, though unlikely, can happen at any time.When your fire extinguisher has been used, even partially, you need to go for refill.
1. The Fire Extinguisher is manually discharged and emptied.
2. The extinguisher is then dismantled completely; cylinder is de-stressed. 3. The cylinder then is made to undergo a Hydro Static Pressure Test at 30kgf cm sq. for 2 minutes to check for leaks and the burst capacity.
4. New extinguishing agent (powder, gas, water or foam) is filled in the cylinder through a vacuum based process that fills the cylinder with exact quantity of extinguishing agent.
5. Fire extinguisher is charged (pressurized) with pure nitrogen.
